Outline of Final Research Achievements

To improve precision measurements using cold molecules for high-energy physics, we have developed cold and slow molecular beams and a superconducting microwave resonator to focus and decelerate the molecular beams. We have also demonstrate the focusing of a molecular beam using a microwave resonator made of a normal conductor. To stabilize the frequency of the detection laser, we have built an ultralow expansion etalon. Using this etalon, we have measured absolute frequencies of some major atomic lines around 400 nm.
